Doesn't being non-binary puts you in another box and actually helps the stereotypes and not FIGHT the stereotypes?

It's a genuine question, I'm confused and I'm trying to understand. As I know people who are non-binary don't want to be labeled as stereotypical female or male and choose to label themselves as non-binary or something else to avoid social constructs. Doesn't that thought process support the social stereotypes of genders and mean that if you are a female or male, you can't be someone like non-binary? Why can't I be called a woman and wear "masculine" clothes? Why can't I be a man and wear make up and dress? If I as a male wear dresses and makeup, am I not erasing the line between socially constructed gender roles and expectations and ACTUALLY help to break these stereotypes? I feel like defining yourself as non-binary is helping the feminine/masculine stereotypes because you think you can't be called a man/woman and be the opposite of the stereotype attached to that sex. Do you think being a woman/man is only those boxes? That is actually reducing women/men to those stereotypical labels society put on them. The only difference,in my opinion,is and should be biological but the rest is up to a person/individual. You can't put whole sex in boxes and say that some certain traits is relevant to every individual and I feel like this is what other genders are doing, it's dividing us even more, because it seems like "I'm not a woman because I am not girly/feminine", like that's the only thing a woman is and can be. I'd like some perspectives on this.
